Changed the entire user interface style.

Several issues:
  - Not able to get the green style ressources appearing on screen (checkbox still blue)
   - Created a LocationController to connect to GooglePlayServices, retrieve location and send it to user interface: This class is not properly functioning for the moment.
   - Tried to add map to a tab of the actionbar: This is not working properly: The app ends when I go to the map for the second time
